Sending static signals, is it possible?

I have a list of entry widgets inside a list and I want the container to be notified if one of them gets selected.
I don't want to connect all the entries idividually so I tought sending a static signal might work

Connections always relay on concrete object instances. It makes no sense for signal to be static, because signal has to come from a "living" object.

You are creating the DeckScrollListEntry objects somewhere, so connect the signals there, too. Alternatively, use automated connections: connectSlotsByName(). I don't recommend it, though, because it is very easy to make a mistake here. The new connection syntax is definitely the best.

I'm not sure if you understood what I was trying to do. It wasn't really clear from what I posted.
Tough I have since realized that it's a horrible design that would lead to all kinds of bugs down the road.
What I was trying to do is something like this

So it would connect to a static signal that is sent by any DeckScrollListEntry.
So in a way it would connect to every DeckScrollListEntry.
And I also realized this is not possible of course, and it would be horrible if it were possible.
